Display not getting signal

[bryan gregory]

Specs - GPU: Radeon HD 7870, Motherboard: Gigabyte GAZ77XUD3H

One morning my monitors suddenly stopped getting signal from my GPU, so I logged into my PC with TeamViewer to see what was going on. My monitors are not broken and furthermore it turns out that my GPU was no longer detected (been working fine for two years). But it doesn't stop there - I tried to plug my monitors into my motherboard after I unplugged the GPU, and the onboard graphics aren't working either. I tried reseating my RAM, did nothing. My guess is that it wasn't the GPU in the first place. Can anyone else take a guess?

in what way did you unplug the videocard, by taking the card out of the case or unplugging the power cord from the psu to the video card?

try clearing the cmos as have found that to work sometimes to kickstart a stubborn system. try another psu even a borrowed 1 with all the drive cables disconnected to see if computer displays post screen or not. how many sticks of ram?

Update: resetting the bios using the cmos switch allowed me to boot with onboard graphics. Either the GPU or its drivers seem to be the issue.

drivers do not run till windows starts loading & if you are not seeing a post screen then the problem is not software but hardware as in bad videocard.
